Please help solve this word problem

Sarah earns 25% more than her friend Lary. Together they make $180 000 per year. What is Lary's salary?

Thank you in advance:)

Let Sarah's salary be S and Lary's salary be L.
If Sarah earns 25% more than Lary. Then S = 1.25L
so S + L = 180000
1.25L + L = 180000
2.25L = 180000
L = 80000

Therefore, Lary's salary is $80 000.

S=1.25L
S+L= 180
(1.25+1)L= 180
L= 180/2.25= 80 thousend
S= 100 thausand
